Probing Explosion Mechanism of Supernova Using Both Gravitational Waves and Neutrinos with Realistic Detector Responses |
|
Abstract |
When core-collapse supernova happens in our galaxy, various detectors would detect gravitational waves (GWs), neutrinos and electromagnetic sources. The detailed explosion mechanism is not understood yet, current numerical simulations show succeeded to introduce multi-dimensional effects, SASI and asymmetric convection. By using a consistent model for both GW and neutrino, we are discussing how supernova signals are observed and investigating explosion mechanism. To investigate the progenitor core rotation, we probed the comparison between start time of GW emission and neutronization burst time is powerful method. To extract their times, we did detection simulation of KAGRA detector and Gd-doping water Cherenkov detectors and developed the method of extraction. Our study showed the potential to investigate core rotation for our galaxy supernova. We submitted to gr-qc/1084593. And, we're focusing on the characteristics signal from SASI and convection phase. To extract frequency information from observed neutrino trigger information, we use the delta-sigma modulator and show the potential for this analysis. |
